BI data is not matching with R3 data after a fresh setup. BI vs R3 Mismatch

Dear Gurus,

Recently we had Implemented the Inventory Management for Retail. Taken downtime and loaded the data by following all the steps. The data is successfully loaded till Nov 2010 to till date. Now when I am comparing the data with R3 using MB51, I am getting the below issues.

We have report in BI, on Material Ledger and we run above query for the duration of 1st Jan 2011 to 31st Jan 2011, This appear to be difference in the output.
